As you explore the game's open world you'll encounter spots called Access Points which are shielded by enemy protection. Upon defeating the enemies, you can access them and unlock map info, save your game or access your inbox for messages. Upon death you also respawn from them. As you explore, you'll find some locked chests you can't access. To learn how, check out the How To Open Locked Chests page.

One locked chest located next to the remains of a truck would allude to NieR: Automata taking place in Japan. "Paper Attached to Vehicle" is a collectible intel record of a traffic violation notice. The traffic violation was issued from Police Constable Kenichi Sato of Maihama Police to Yosuke Saito in 2013. Kenichi Sato is the president of Platinum Games and Yosuke Saito is an executive producer of Square Enix. While amusing, this information would point to NieR: Automata taking place in Urayasu, Japan, as Maihama Station is located there. Urayasu is a city in the Greater Tokyo Area, the in game location of NieR: Gestalt/Replicant. Coincidentally, Urayasu is home to Tokyo Disney Resort, a location possibly represented by the Amusement Park area. Another piece of anecdotal evidence would be the in game location of Kaine's Shack, both in NieR: Gestalt/Replicant and NieR: Automata.

"Paper Attached to Vehicle" is located in a locked chest near the remains of a truck. Can be reached from City Ruins: Near Factory Access Point as 9S.
